Description
Technical Field
The utility model relates to an indirect evaporation cold water treatment technical field especially relates to EC-J indirect evaporation cold water treater.
Background
The indirect evaporative cooling circulating water system mainly utilizes the evaporation latent heat of water and discharges the heat of the evaporative cooling air conditioning unit to the atmosphere through the evaporation effect of water in the spray tower, thereby ensuring the normal work of the air conditioning unit. Because the evaporation action of the spray tower discharges a large amount of pure water into the atmosphere in a gas form, a large amount of organic matters and inorganic matters are continuously concentrated in circulating cooling water, the circulating water quality is gradually deteriorated, the biological slime breeding of the spray tower is caused, the heat transfer efficiency is influenced by the surface scaling of the heat exchange core body, and the like, the heat exchange efficiency is reduced, and the service life of equipment is shortened. Therefore, in order to ensure the good operation of the circulating cooling water system, save energy consumption and reduce drainage, the necessary water treatment means is adopted to ensure the water quality of the circulating water, and the method has great economic significance and social significance. At present, the methods commonly used for the treatment of circulating cooling water mainly include chemical agent methods, ion exchange methods and various physical field water treatment methods.
The chemical agent method is a traditional water quality treatment method, and the used agents comprise scale inhibitors, corrosion inhibitors and biocides. The scale inhibitor has the function of destroying the crystallization process of insoluble matters in water, so that the growth of scale is prevented within a certain range; after the corrosion inhibitor is put into water, a thin protective film can be formed on the surface of the metal to passivate the surface of the metal, so that the process of metal corrosion is greatly slowed down; the biocide has an inactivating effect on bacteria, algae, etc. after reaching a certain concentration in water, and can inhibit the growth of the bacteria, algae, etc. The chemical method has a remarkable effect on controlling the quality of circulating cooling water, but since the added chemical is consumed in the water, it should be replenished. On one hand, the requirement of the regular and quantitative supplementary medicament on operation and maintenance personnel is higher, and the situation of poor water quality control caused by insufficient medicament addition often occurs in practical application; or waste is caused by excessive adding of the medicament or side effects are brought to the system due to overhigh concentration of the medicament; on the other hand, the continuously consumed medicaments inevitably require special persons to purchase the medicaments and store the medicaments in special places, so that the maintenance workload is large, and the operation cost is high.
The ion exchange method mainly adopts sodium type ion exchange resin, and sodium ions in the resin and calcium and magnesium ions in water are subjected to replacement reaction, so that the hardness of the water is greatly reduced. This method has remarkable effects of controlling the formation of scale in the circulating cooling water, increasing the concentration ratio and reducing the amount of discharged water, but the resin needs to be regenerated periodically with saturated brine, so that a large amount of sodium chloride needs to be consumed in the operation process, and the operation cost is higher than that of the chemical agent method. On the other hand, the ion exchange method is only used for scale prevention and inhibition, and other technologies and methods are still needed for controlling the growth of microorganisms in water.
The physical field water treatment method has the advantages of simple and convenient operation and maintenance, low running cost and the like, and is increasingly widely applied to a circulating cooling water system in recent years. Such methods mainly include two main categories: the electromagnetic water treatment method and the high-voltage electrostatic water treatment method mainly distribute salts in water in a fixed sequence through electromagnetic action, so that collision among the salts and between the salts and a metal wall is reduced, and the probability of scale generation is reduced. Therefore, the method has a certain effect on scale prevention, but enough evidence for sterilization and algae removal is still insufficient in theory, and the sterilization and algae removal effects are not ideal in practical application.
